Morphological variation of the relictual alveolar structures in the mandibles of baleen whales [PDF]
PeerJ, 2021 Living baleen whales (mysticetes) are bulk filter feeders that use keratinous baleen plates to filter food from prey laden water. Extant mysticetes are born entirely edentulous, though they possess tooth buds early in ontogeny, a trait inherited from ...

Mechanical plaque removal in step‐1 of care
Periodontology 2000, EarlyView., 2023 Abstract Maintaining a regular oral hygiene routine is essential for taking care of our mouths, ensuring healthy teeth, and achieving fresh breath. Patient education on oral hygiene is an important component of their overall treatment. Firstly, patients should be informed about the direct connection between bacteria in dental plaque and oral diseases ...

Baleen Hydrodynamics and Morphology of Cross-Flow Filtration in Balaenid Whale Suspension Feeding. [PDF]
PLoS ONE, 2016 The traditional view of mysticete feeding involves static baleen directly sieving particles from seawater using a simple, dead-end flow-through filtration mechanism.

Oil adsorption does not structurally or functionally alter whale baleen [PDF]
Royal Society Open Science, 2019 Mysticete whales filter small prey from seawater using baleen, a unique keratinous oral tissue that grows from the palate, from which it hangs in hundreds of serial plates.

Lethal entanglement in baleen whales [PDF]
Diseases of Aquatic Organisms, 2011 Understanding the scenarios whereby fishing gear entanglement of large whales induces mortality is important for the development of mitigation strategies. Here we present a series of 21 cases involving 4 species of baleen whales in the NW Atlantic, describing the available sighting history, necropsy observations, and subsequent data analyses that ...

The recovery of Antarctica’s giants – baleen whales
, 2023 - Baleen whales are predominately summer visitors to Antarctic waters, where they feed on large swarms of zooplankton, primarily Antarctic Krill (Euphausia superba).

Frontiers in Marine Science, 2023 In the Southern Hemisphere, baleen whales generally undertake migrations between productive feeding grounds at high latitudes and breeding grounds at lower latitudes. Pygmy right whales (Caperea marginata) (PRW) are the smallest and most enigmatic baleen

RETRACTED ARTICLE: Lateral palatal foramina do not indicate baleen in fossil whales
Scientific Reports, 2022 Today’s mysticetes filter-feed using baleen, a novel integumentary structure with no apparent homolog in any living mammal. The origins of filter-feeding and baleen can be informed by the fossil record, including rare instances of soft tissue ...

Prolonged baleen hormone cycles suggest atypical reproductive endocrinology of female bowhead whales
Royal Society Open Science, 2023 Serial measurements of hormone concentrations along baleen plates allow for reconstructions of mysticete whale reproductive histories. We assessed gestation and calving interval in bowhead whales (Balaena mysticetus) by measuring progesterone, oestradiol,

Oral cavity hydrodynamics and drag production in Balaenid whale suspension feeding. [PDF]
PLoS ONE, 2017 Balaenid whales feed on large aggregates of small and slow-moving prey (predominantly copepods) through a filtration process enabled by baleen. These whales exhibit continuous filtration, namely, with the mouth kept partially opened and the baleen ...
